Version 8.4 does not support single appliances that host both Forcepoint Email Security, Forcepoint Web Security, or Forcepoint URL Filtering. These appliances, known as Dual Mode appliances, have always been limited to the V Series platform.

Before upgrading a Dual Mode appliance to v8.4, either the email or web module must be migrated to a new Forcepoint appliance. To ease the migration effort, special tools have been developed, and a special procedure is recommended. For details, see Upgrading V Series Dual Mode Appliances to Version 8.4. Contact your Forcepoint account representative to learn about special promotions for Dual Mode deployments planning a v8.4 upgrade.

In version 8.3 and later, the V Series Appliance Manager is replaced by the Forcepoint Security Appliance Manager (FSAM). The Forcepoint Security Appliance Manager was released in 2017. In addition, Forcepoint appliances can be fully and completely configured and monitored with the Command-line interface (CLI). And, of course, the CLI remains available now that the Forcepoint Security Appliance Manager is released.

If your appliance hosts Forcepoint Email Security and you must change the C interface IP address, follow the procedure in the Changing the C Interface IP Address technical article.

If your appliance hosts Forcepoint Web Security, changing the C IP address requires a full reinstall (re-image) of the appliance. See the knowledge base article How to restore a Forcepoint appliance to a v8.4.x factory image.
